' This invention relates to new and useful improvements in roof and wallcoverings.

An object of the invention is to provide an improved covering which maybe easily and quickly applied to either or both of the roof and walls ofa structure.

Another object is to provide a covering for roofs and/or walls and whichcompletely covers the roof and/or walls, and in addition to beingcompletely weatherproof is attractive in appearance and is free toexpand and contract with a minimum of visible distortion, undertemperature changes.

A further object is to provide an improved method of applying a coveringto a building structure and by which method the roof and/or walls of thestructure may be quickly and effectively covered.

Another object is to provide a structure which may be applied by workingfrom the top down so that, in laying a roof for example, it is notnecessary for the workmen to walk on the finished roof with consequentdanger of damaging it.

Still another object is to provide a metal roof or side wall coveringwhich can be applied without solder so that the metal can expand andcontract without breaking the joints.

Other objects and advantages will become apparent from a considerationof the following detailed description taken in connection with theaccompanying drawings wherein a satisfactory embodiment of the inventionis shown. However, it is to be understood that the invention is notlimited to the details shown but includes all such variations andmodifications as fall within the spirit of the invention and the scopeof the appended claims.

Fig. 12 is a section thereof substantially on line l2--l2 of Fig. 11;and

Fig. 13 is a section substantially on line l3--|3 of Fig. 11.

Referring in detail to the drawings, in Fig. 2 is shown a ham or otherbuilding structure Ill the side walls ll of which are covered accordingto the present invention. The same covering may be applied to the roofalso. The sheathing of the walls of the structure is'designated l2 andthe improved covering over the sheathing comprises joint strips l3 andfacing sheets l4 covering the building structure between the jointstrips.

Preferably the joint strips and the facing sheets are of rolled copper,the joint strips being preferably of about eight ounce copper or about012 inch thick and fourinches wide and the facing sheets beingpreferably of about three ounce copper or about .004 inch thickandtwelve inches wide. However, the dimensions, weight and material may beother than suggested, and I am not confined to the use of copper asother metals may be used, as for example brass, galvanized iron,aluminum or other suitable metal.

The metal should preferably be soft or dead with no, or practically no,spring or resiliency so that it may be more easily bent to proper shapeand position and will remain there after being bent.

The joint strips [3 each comprise an elongated body including a flatattaching portion l5 along one of its longitudinal edges and having apart including its other edge bent or folded to extend upwardly andoutwardly at l6 and then downwardly and outwardly at ll. Then the partis bent back upon itself providing portions l8 and I9 substantiallyparallel with the portions l1 and l6. Thus the strip includes a doublewalled upwardly and outwardly directed part having its intermediateportion extending downwardly and outwardly. Itis formed with theportions I6 and I9 spaced from each other for insertion of the upperedge of sheet or strip i4.

Facing sheets M are also elongated and of relatively thin metal and eachhas a sheet of felt or other insulating material 20 secured to its rearsurface as by an asphalt or other adhesive 2|. The insulation 20 stopsshort of the longitudinal edges of the metal for a reason presently toappear. This felt is a sound deadener and heat insulator. It alsofacilitates handling of the thin copper without crinkling.

In applying the covering to'a building structure joint strips aresecured to the structure as by a row of nails 22 driven through theupper portion of the fiat portion [5 of the strip. These strips arespaced 9. given distance depending on the width of the strips or sheetsl4. If the strips or sheets M are 12 inches wide then the joint stripsare spaced with their upper edges 9 inches apart. As originally securedin place the strip has its bent or folded portion extending outwardlyfrom the wall of the structure as shown in Fig. 4.

Next a facing sheet I is placed against the structure and its upperlongitudinal edge portion 23 is inserted into the double wall foldedpart of the securing strip, being arranged between the portions l6 and99 thereof as in Fig. 4, and as shown at joint A in Fig. l. Thereafterthe folded part of the joint strip is bent down to the position shown inFig. 5 and also shown at joint B of Fig. 1. This results in the upperedge portion 23' of the facing sheet being bent downwardly forming ahook=1ike part in the fold of thesecuring strip, and it is noted thatthe bent portion of the facing strip is beyond the felt or insulation20. After this folded part is thus bent down a second row of nails 220.may be applied just above the fold and below the first row 22, andpreferably staggered in respect to it as shown at joint B in Fig. 1.

Either before or after the facing sheet has its upper edge portion bentinto the fold of the upper joint strip a lower joint strip is secured inplace in such spaced relation to the upper joint strip that the facingsheet will cover the space between them.. Following the securing of theupper edge of the facing sheet its lower edge portion 24 beyond theinsulation 20, is folded or bent about the folded double walled part ofthe next lower joint strip, extending about the intermediate offsetportion thereof as shown in Fig. 5.

Thereafter the intermediate ofiset portion l1, l8 of the folded part ofthe joint strip is folded up against the main portion of the folded partas in the upper portion of Fig. 6 and as shown at joint C in Fig. i.There it will be seen that the upper edge portion of one facing sheet isfolded into the main part of the fold of the joint strip and that thelower edge portion of the upper facing sheet is also feided .into thejoint, being located at the inner side of the oflset portion l1, l8 ofthe folde-d'part.

The joint is finished by folding the same down into the position shownin the lower portion of Fig. 6 and at D in Fig. 1. This is the finishedjoint and attention is directed to the fact that the facing sheetextends over the securing portion l5 of the lower joint strip coveringthe securing means passing therethrough. It will also be seen that thefacing sheets or strips I4 entirely cover the joint strips l3. Theinsulation 20 may be stopped either at the upper edge of the securingportion of a lower joint strip as in Figs. 5 and 6 or it may be ofgreater width so as to extend over such portion as in Fig. 1.

The metal used is preferabiy soft copper non- ,resilient so as to beeasily bent and so as to stay in any position into which it is bent. Itmay be folded by hand or with tongs or other tools as required.Preferably when making the final fold, that is when folding the jointfrom the position shown in the upper portion of Fig. 6 tothe positionshown in the lower portion of said figure, a wooden block covered withburlap or the like is used. Such a blockwould be placed against thejoint and hammered so as to bend the joint into place without damagingor denting it.,

It will be understood that as each facing sheet is apphed its upper edgeportion is first secured and thereafter its lower edge portion issecured. Such being the case a workman can start the job from the topand work down and therefore is not required to work on the finished partof the covering and will not damage it.

The covering is applied without the use of solder, the facing sheetsbeing secured by having their edge portions folded into portions of thejoint strips forming weathertight seams. Since no solder is used in theseams the covering can expand and contract with temperature changes. Thejoint strips may be arranged in abutting relation at their ends ifnecessary as they are entirely covered by the facing sheets, but it ispreferred that the facing sheets be of sufficient length to extend fromone end to the other of a roof or wall.

The felt 20 is a sound deadener, and to faciiitatc handling of the thincopper withouthaving it crinkle. At spaced intervals along its lengtheach facing sheet is provided with folds 25 extending transverselythereof as shown best in Fig. 1. They are formed by merely folding themetal over on itself as shown. Primarily these folds are forarchitectural effect to break up unsightly reflections, due to bucklingof a long continuous sheet, resulting in a better appearance. Also thefolds tend to absorb expansion and contraction. As shown in Figs. 1 and2 the facing sheets are preferably so arranged that the transverse folds25 of each sheet are in staggered relation to those of the adjacentsheets. This breaks up the surface and gives a much better appearance.

In Figs. 7 to 10 is shown a somewhat simplified construction which maybe used for side walls, and also roofing, particularly on steep slopes.The principle is the same as that of the previous figures but the jointstrip is somewhat simplified while the facing strip or sheet is the sameas that of the first form. It will be seen that in this modifiedconstruction the joint strip 26 in proper spacing as in the first formwith the nails 22 and then the upper edge 23 of the facing sheet I4 isinserted as indicated in Fig. '7. Then the loopedportion 28, 29 is bentdownwardly to the position shown in Fig. 8. This also bends the upperedge portion 23 of the facing sheet downwardly to form a sort of hook tosupport the sheet as shown. While in this position the second row ofnails 22a. may be applied. Then the lower edge portion 24of the facingsheet l4 next above may be folded around the looped portion 2-9, 29 ofFig. 8 to cover and enclose it as shown in Fig. 9. Then to finish "thejoint the loop 28, 29 enclosed in the folded portion 24 is bent down tothe position of Fig. 10 to complete the application, the

folding operation being by the same means as 7 suggested in connectionwith the first form. It will be seen that in this simplified form as inthe first form the joint strips 25 are completely enclosed by the facesheets M.-

In Figs. 11 to 13 is shown a somewhat modified construction of thefacing sheets. These sheets indicated as a whole by numeral 30 are thesame as sheets l4 except that the central or body portion between theupper plane portions 23 and the lower plane portions 24 (not shown) iscorrugated with vertical corrugations as shown at 3|. These corrugationsare carried down to about the lower edge of the felt backing 20 leavingthe lower portion 24 plain to be folded around the next lower jointstrip. These corrugations relieve the plane surface and break upunsightly reflections and also allow for expansion and contraction. Thefolds 25 of the first form are ordinarily not needed with this form butmay be used if desired. The felt20 is used on the back of the facingsheets in this form the same as the first form and may be secured to itbythe same means such as cement 2|.

Having thus set forth the nature of my intween the spaced foldedportions of the upper joint strip and with its free edge adjacent thefold of said folded portions, said upper joint strip having its foldedportion bent down and substantially parallel with the outer surface of.the facing sheet, said lower joint strip having an inwardly andupwardly folded portion, and said facing sheet having its lower edgeportion bent inwardly and upwardly about the folded portion of the lowerjoint strip.
